Deploying Web App With Spring MVC

Question

I have never come across this problem before. Actaully, I have a web application running through a war file. I have configured Spring to work with it and it works perfectly.

The problem is that I am trying to configure Activiti through Spring. Basically, there is a set of .bpmn20.xml files inside the WEB-INF/processes folder. The Activiti team has mentioned that they do not know how to configure this inside a web application. As a standlone application I can deploy resources .bpmn20.xml files automatically as the processes folder is on the classpath. I have having trouble configuring in a web application structure.

Please see below:

I am created a Spring MVC application and created an Activiti database by running the DbSchemaCreate.main(). Actaully my processes don't seem to deploy on the war file. When Tomcat starts the ProcessEngine is started through Spring and works. I can access the RuntimeService. The code can be seen below:

web.xml

The automatic resosource deployment is not being deployed. I have also tried through the code to deploy but it throws an Exception:

 repositoryService.createDeployment().addClasspathResource("ProcessExample.bpmn20.xml").deploy();
 runtimeService.startProcessInstanceByKey("processExample", mapOfProcessVariables);

How can this resource be located inside the webapp?

I have tried putting it in WEB-INF/processes/ProcessExample.bpmn20.xml.

I have also tried:

<property name="deploymentResources" value="/WEB-INF/processes.*.bpmn20.xml"/>

EDIT

This website may help, but I am stuck.

Is WEB-INF in the CLASSPATH?

Maybe try adding the folder where the process is defined (your bpmn20.xml file) to the build path.

The error tells you, that the Activiti-Engine cannot find your file, that's why you need to tell it where to find it.

Try This :

Above code is spring-config.xml

Add database.properties file in resources folder of src folder. So write code in database.properties

database.driver=com.mysql.jdbc.Driver
database.url=jdbc:mysql://localhost:3306/apmc_db
database.user=root
database.password=
hibernate.show_sql=true
